摘要: Provided are: a liquid crystal display device capable of rapidly removing residual electric charges in a panel when a power supply is turned off, and in particular, suitable for a case where IGZO-GDM is adopted; and a driving method of the liquid crystal display device.In the liquid crystal display device, when an OFF state of the power supply is detected, a power supply OFF sequence including an initialization step, a first discharge step and a second discharge step is executed. In the initialization step, only a clear signal (H_CLR) among GDM signals is set at a high level, and a state of each of bistable circuits which constitute a shift register is initialized. In the first discharge step, only the clear signal (H_CLR) among the GDM signals is set at a low level, all of gate bus lines are turned to a selected state, and electric charges in pixel formation portions are discharged. In the second discharge step, the clear signal (H_CLR) is set at the high level, and electric charges on floating nodes in each of the bistable circuits are discharged.

摘要: The invention provides a liquid crystal display device that includes an IGZO-GDM which can quickly remove a residual charge in a panel when the power supply is turned off, and a driving method of the liquid crystal display device. Each bistable circuit that configures a shift register includes a thin film transistor TI for increasing a potential of an output terminal based on a first clock, a region netA connected to a gate terminal of the thin film transistor TI, a thin film transistor TC for lowering a potential of the region netA, and a region netB connected to a gate terminal of the thin film transistor TC. In such a configuration, a power supply off sequence includes a display off sequence and a gate off sequence. The gate off sequence includes at least a gate-bus-line discharge step (t14 to t15), a netB discharge step (t15 to t16), and a netA discharge step (t16 to t17).
